Art Generator Asset Guidelines

Learn how to organizing your art files for your NFT generative collection. This guideline works both for Open Generative Collection and using NiftyKit Desktop Art Generator

By the end of this guide, you'll learn how to set up your file structure, export your files from Photoshop, and organize them into proper folders. No action is required from you, but we encourage you to watch the video to gain a better understanding of the process.

Folder Organization

Ensure that the traits are organized in a folder structure, with the folder name being the name of the trait category and individual files under the folder are traits.

Ensure that folders are named with the layering order, 0 being the bottom-most layer. The layering order should come first, then the underscore, and then the name of the trait category.

Example:

  • 0_Face

    • Oval.png

    • Round.png

    • Square.png

  • 1_Eyes

    • Round.png

    • Three Eyes.png

    • Anime.png

  • 2_Hair

    • Pink.png

    • Blue.png

    • Curly Black.png

  • 3_Weapon

    • Sword.png

    • Mace.png

    • Nunchaku.png

Rarity

Rarity is defined by which trait will have a higher chance of appearing, almost like throwing a dart on a board.

For example:

0_Face
- Oval.png
- Round.png
- Square.png

This setup will have an equal chance of getting each trait.

If we want to introduce rarity, we use the __r and a number assigned to it:

0_Face
- Oval__r1000.png
- Round__r1.png
- Square__r500.png

By appending rarity numbers, this setup says Oval has a 1000/1501 chance of getting it, Round has a 1/1501 chance, and Square will have a 500/1501 chance.

Lower the number, rare it is.

Empty Traits

Sometimes we want traits that don’t show up, and best way to do that is to create an empty transparent PNG file, called “None” or “Empty” whichever makes sense for your collection. For best results, try to keep the Empty file the same size dimension as your other layers.

0_Face
- Oval__r1000.png
- Round__r1.png
- Square__r500.png
- Empty__r10000.png

This will have 10000/11501 chance of getting an empty face.

Conditional Groups (new)

Sometimes, we have 2 traits that just simply doesn’t belong together.

Conditional groups allows only 1 of the “group” members to be selected. We use the __g and a number to specify the conditional group.

0_Face
- Oval__r1000__g1.png
- Round__r1.png
- Square__r500.png
- Empty__r10000.png
1_Eyes
- Round.png
- Three Eyes__g1.png
- Anime.png

Because the layering logic works in sequential order (starts with Face, then Eyes), if Oval is selected, then Three Eyes will never be selected.

Blend Modes (new)

The custom blend option can be one of clear, source, over, in, out, atop, dest, dest-over, dest-in, dest-out, dest-atop, xor, add, saturate, multiply, screen, overlay, darken, lighten, colour-dodge, color-dodge, colour-burn,color-burn, hard-light, soft-light, difference, exclusion.

You can read more about it here:

You can apply any custom blend modes to any layers:

0_Face
- Oval__r1000__g1__color-burn.png
- Round__r1.png
- Square__r500.png
- Empty__r10000.png
1_Eyes
- Round__darken.png
- Three Eyes__g1.png
- Anime.png

By default, is set to over which will allow the image to be placed on top of the previous layer.
